Pneumatic device for improving lift co-efficient of aircraft wing - is inflated with compressed air stored in pressure vessel in aircraft, air flowing in flexible duct forming leading edge of wing

摘要

A mass flow measurement arrangement has a flow inlet, a channel (2) carrying the flowing medium, a channel outlet, a drive which rotates the channel and a device for measuring the Coriolis forces. The channel is formed in a spherical or circular cylindrical rotor (7) rotatably mounted in a housing (9) forming the stator. The outlet (3) and inlet (1) are implemented in the stator and are coaxial with the channel ends. The channel drive, e.g., an electric motor, is partially implemented in the rotor and partially in the stator. USE/AVANTAGE - Eliminates disadvantages of vibrating channel devices associated with damping and fatigue.
